INDOOR AIR QUALITY TESTING
PM2.5 & PM10
Ottawa Indoor Air Quality Testing
Air quality within buildings and structures can affect the health and comfort of occupants by chemical exposure, toxic or irritating gases, particulates, or biological materials (mold and bacteria)
We provide indoor air quality testing and inspections in the greater Ottawa area.
We measure onsite in real time for:
• Relative Humidity
• Volatile Organic Compounds (TVOC)
• Carbon Dioxide (CO₂)
• Carbon Monoxide (CO)
• Nitrogen Dioxide (NO₂)
• Nitrogen Oxide (NO)
• Formaldehyde (HCHO)
• Ozone (O₃)
• Ammonia (NH₃)
• Sulfur Dioxide (SO₂)
• Hydrogen Sulfide (H₂S)
• Airborne Particulate PM₁₀ PM₂.₅
• Combustible Gases
We also a perform sampling for airborne mould, surface mould, indoor allergens, bacteria, endotoxins, radon testing and odor investigations.
Collecting air samples and testing for mould & spores is not an Indoor Air Quality Assessment. The indoor environment can have many more potential contaminants or contributors to compromised indoor air quality than just mould. Unfortunately, many inspectors are selling a mold test as an indoor air quality test.
A commercial building ventilation assessment would include outdoor air calculation, air handling unit and VAV inspection. Insufficient ventilation is one of the most common IAQ problems. Gravelle Building Environments Inc. has extensive experience in commercial ventilation systems, including development of strategies to achieve appropriate outdoor air and carbon dioxide levels through ventilation and H.V.AC. controls.
Many buildings are plagued by dust mites and cockroaches which leave a trail of allergenic feces and body parts. Fumes from rodent urine and droppings can also cause breathing problems, as can pet dander and airborne proteins from cat saliva. On top of that, indoor air may be invaded by pollen and bacteria from outside.
